A blueprint for a garage has a scale of 1.5 cm to 3 m. On the blueprint, the length of one wall is 8 cm. If w represents the length of the actual wall, what is w?
what is the answer
The answer would be 16m
To find the length of the actual wall, we need to use the given scale.
The scale on the blueprint is 1.5 cm to 3 m. This means that for every 1.5 cm on the blueprint, the corresponding length in real life is 3 m.
We know that on the blueprint, the length of one wall is 8 cm. So, we can set up a proportion to find the length of the actual wall:
1.5 cm / 3 m = 8 cm / w
To solve this proportion, we can use cross-multiplication:
(1.5 cm) * (w) = (3 m) * (8 cm)
1.5w = 24
Now, we can solve for w by dividing both sides of the equation by 1.5:
w = 24 / 1.5
w = 16
Therefore, the length of the actual wall is 16 meters.
A blueprint for a garage has a scale of 1.5 cm to 3 m. On the blueprint, the length of one wall is 8 cm. If w represents the length of the actual wall, what is w?
A. 4 m
B. 6 m
C. 8 m
D. 16 m
each 1.5 cm represents 3m
So, how many times bigger is 8 than 1.5? There will be that many 3m lengths. So, the real length is
8/1.5 * 3
